CHANGEABLE HEADLIGHT.

To a7] 101mm if may concern.

Be it knownthat we, ViCToR HOWARD and Jamas P. illumini', citizens of the United States', residing at Oakland,A in the county7 of Alameda and State of California, have invented new and useful Improvements in Changeable Headlights, of which the following is a specification.

In traveling in a sharp curve, or turning' a corner, the head-light of an automobile, fiXedly secured upon its body, does not illuminate the'path over which the wheels are traveling.

It is the object of our invent-ion to provide means for rcmedying this defect.

In the accompanying drawing, Figure 1 is a side view ofthe front portion of an automobile equipped' with our invention, parts unnecessary thereto being omitted; F ig. 2 is a diagrammatic view of the electri cal connections; Fig. 3 is an enlarged sec-Y tional View of the switch for making said connections; Figs. 4 and 5 are sections on the line 4-4, 5`5, respectively, of Fig. 3.

, Referring to the drawing, 1 indicates the body of an automobile, 2 the steering wheel, and 3 the steering post thereof. Two headlights 4 are here shown, although our inthe central reflector.

vention is equally applicable to a single head-light, and insteadof confining'each head-light to a single electric lamp 5, and reflector 6, we provide in each head-light, in addition to the central reflector 6, side reectors 7 andelectric lamps S therefor, said side reflectors directing the light at an angle of 45 degrees, to the right and left respectively, of the direction vof the light from The reflectors of each head-lightare all comprised in the same casing, and are each in the general form of a cone somewhat flat. at. the top,'and are stationarily secured upon the frame of the car,but only one lamp in each head-'light 'is illuminated at any time, the central lampv 5 being illuminated when the car is't-ravel'- ing straight ahead. or approximately so, the right hand lamp when traveling to the right, and the left hand lamp when traveling to the left. To accomplish this result we provide an electric switch 9 automatically operated with the turning of the steering wheels, the construction of which is as follows z-11 indicates a casing secured to the Speccaton of Letters Patent.

body of the car at any suitable point,`prcf` erably in a position in which the switch can be directly geared to the" steering post 3. Upon said steering post is formed a worm 12 which meshes with a wornnsehment 13 secured by a screw 15 on a sleeve 14, surrounding a shaft 17 and secured by ascrew 16 to said shaft. Upon said shaft" 17 within said casing is secured a sleeve 18 of insulating material formed with a -central annular rib 19. one side of said rib extends' a metallic ring Around said sleeve on 21 having a projection 22. Said projection contact 24, and the extension 23 is out ofI contact with two spring electric' contacts 25. The ring 21 is always in electrical contact with an arcuate spring 26, connected to a i binding post 27, to which is connected a wire 28 leading to onejside of the source 29 of supply of electricity, while the spring contacts 24, 25 are connected to binding posts 31, 32, connected by wires 33, 34, 34, lead# ing through the several lamps, or through them in parallel, if there are a plurality of head-lights, wires 35, 3G leading therefrom to the other side of said source. In the straightahead position of the car, the project-ion 22 contacts with the contact 24, and the current Hows through the central lamp of the head-light. But, on turning the steering wheel through a sufficient angle to one side the projection 22 breaks contact with the spring contact 24, and the extension 23 makes contact with one or the other of the spring contacts 25, and a current flows through one or the other of the side lamp -side lights coincide to a small extent, so as to prevent darkness in passing from one light to the other.

We claim In combination with automobile steering mechanism central and side electric lamps, individual reflectors for the severallanips,

the reflector for the central lamp directlng the light straight ahead, and the reflectors for the side lamps directing the light at an angle with the direction by the central re- Hector, a circuit for each lamp, and means,

operated automatically with the operation of said steering mechanism, for breaking the ycircuit through one of the'lamps and ,15

closing that through another lamp.

In testimony whereoi` we have hereunto set our hands in the presence of two subscribing witnesses.
